ROTARY BRUSH.

Application mea october 1s, 19'21. semi m. 507,422.

To all whom it may concern:

Be it known that I, Armmr L. Norms, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in Rotary Brushes, of which the following is a speclication. l

This invention relates to rotary brushes, and more particularly t'o a brush having a casing in which a motor is arranged, the motor being connected to the brush by suitable gearing to drive it.

In the present invention, I have provided a motor driven rotary brush suitable for use in scrubbing clothes or in any other manner wherein a driven brush is desired. The brush is portable, permitting it to be moved over the surface of the cloth or other material being cleaned, and is provided with a handle for the purpose of easy manipulation.

A casing is provided for the rece tionof the motor by means of which the rush is driven and the brush is arranged on the bottom of the casing, permitting it to be passed over the material to be cleaned in a manner similar to an ordinary sad iron in pressing. Suitable gearing is provided to reduce the speed of the drive and thus ermit the use of a small motor which is easily portable.

In the accompanying drawmgs, I have shown several embodiments of the invention. In this showing:

Figure 1 is a vertical sectional view,

Figure 2 is a horizontal sectional view on line 2-2 of Figure 1,

Figure 3 is a similar view on line 3-3 of Figure 1, and,

Figure 4 is a'detail view of a modified form.

Referring to the drawings, the numeral 1 designates a casing which may be made of any suitable shapev and size and which is provided with a tubular extension 2 for the reception of the handle 3. Lead wires 4 extend through the handle, and a suitable control member or switch 5 is mounted on the tubular extension 2. A motor 6 of any suitable ty e is arranged within the casing, the motor Being rov1ded with a main shaft 7 and supporte in a bearing 8 in the top of the caslng, and a bearing 9 in the bottom of the casing. The bearing 9 is carried by a base plate 10, secured to the casing in anyy suitable manner. As shown, the shaft extends through the base plate. The base plate is provided with a passage 11, extending into the bearing 9 and registering at its outer end with an opening 12 in the casing to permit oil to be introduced to the bearing. Beneath the base plate, the shaft is provided with a pinion 13 secured to the shaft by means of a key 14. A plurality, of idler gears 15 are loosely mounted on pins 16, the pins being provided with threaded portions 17 adapted to be received in bosses 18, carried by or formed on the base plate. These idler gears are adapted to mesh with a ring gear 19, formed on the flange of a plate 20, the plate being loosely mounted on the main shaft. A connecting plate 21 is arranged beneath the center of the plate 20, the connecting plate being provided with a flange 22 adapted to be received in a recess in the plate 2O and secured thereto by means of fastening elements 23. The-plate 2() is maintained on the main shaft by means of a Washer 24, and a nut 25. A stub shaft 26 is formed on the connecting plate and is adapted to receive a gear 27, keyed thereto, as at 28. This gear meshes with idler gears 29 which are mounted ony stub shafts 30, carried by an intermediate gear housing 31. The intermediate gear housing is secured to the base plate by means of fastening elements 32. A ring gear 33 meshes with the gears 29 and this gear is provided with a downwardly extending flange 34. The brush is provided with a base plate'35, having a flange 36 which is secured to the flange 34 by means of fastening elements 37. The brus proper is secured to the plate 35, as shown. The brush comprises a body portion 37 having bristles 38 secured thereto. A ring 39 is secured to the intermediate gear housing and this ring is provided with a yhorizontal flange 40, adapted to be arranged beneath the ring gear 33 to retain it in position. The upper surface of the ring gear is provided with a convertA rib 41, adapted to be received in a recess in the adjacent face of the intermediate ear housing to prevent the brush from Wa bling. l

The intermediate gears are oiled through an oil hole 42 in the base plate, and the gears 29 and 33 are oiled through an oil hole 43. In the form of the invention shown in Figure 4 of thedrawings, the rin gear 33 1s provided with aplurality of ri s 44 adapted to be received between similar ribs 45 carried by the intermediate gear housing to hold the brush steady at all times.

. the motor is on, the main shaft 7 drives the pinion 13 which in turn drives the idlers 15 and the ring gear 19. This drives the connecting plate 21, rotating shaft 26and pinion 27. A inion 27 drives the idler gears 29 which 1n turn drive the ring gear;

33 to which the brush is connected.

It is to be understood that the forms of my invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size, and arrangement of parts may be'resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

I claim:

1. A brush comprising a casing, a motor arranged therein, a motor shaft driven by `said motor, said motor shaft projecting from said casing, a pinion mounted on said motor shaft, a series of planetary gears meshing with said pinion, av connectlng plate secured to a portion of said series of gears, a pinion secured thereto, a lbrush head rotatably mounted on said casing adjacent said pinion, and gearing meshing with said inion and adapted to rotate said brush an head.

2. A brush comprising a casing, a motor arranged therein, a motor shaft driven by said motor, a pinion mounted on said shaft within said casing, a series of planetary gears meshing with said pinion, said casing being provided with an opening adjacent said series of planetary gears, a rotating member secured to a portion of said series of planetary gears and projecting through said opening, a brush head rotatably mountedl on the exterior of said casing adjacent said opening, and connections between said connecting plate and said brush head to drive said brush head.

3. A brush comprising a casing, a motor arranged therein, a motor shaft driven by said motor, a pinion mounted on said shaft, a series of planetary gears arranged in said casing and meshing with said pinion, a rotating member connected to a portion of said series of planetary gears, said casing being provided with an opening through which a portion of said rotatin member extends, a pinion carried by sai rotating member exteriorly of said casing, a brush connecting plate secured to said ring gear,

"a pinion secured thereto, a brush head rotatably mounted on said casing adjacent said pinion and gearing meshing with said pinion and adapted to rotate said brush head.

5. A brush comprising a casing, a' motor arranged therein, a motor shaft drivenl by Said motor, a base plate arranged beneath said casing, said motor shaft extending through said base plate, a ear housing arranged beneath said base p ate and secured thereto, a pinion mounted on said motor shaft beneath said base plate, gearing arranged in said housing and meshing with said pinion, said housing being provided with anvopening, a stub shaft extending through lsaid opening, a ring gear arranged beneath said housing, gearing connecting said shaft, to said ring gear, a brush head secured to said ring gear, and apmember secured to said motor housing and engaging said ring gear to prevent displacement thereof. l

6. A brush comprising a casing, a motor arranged therein, a motor shaft driven by said motor, a base plate arranged beneath said casing, said motor shaft extending through said base plate, a gear housing arranged beneath said base plate and secured thereto, a pinion mounted on said motor shaft beneath said base plate, avseries of planetary gears meshing with said pinion, a connecting plate secured to a portion of said series of planetary gears, said housing being provided with an opening through which said connecting plate extends, a pinion carried by said connecting plate, a brush head rotatably mounted on said casing beneath said housing, and connections between said pinion and said brush head to drive the brush head.

In testimony whereof I affixmy signature in presence of two witnesses.
